Title: Velocity modulation system for television receiver
Inventor: AKASAKI SHINICHI
IPC: H04N5/445
Filed: 1991-07-17
Abstract: PURPOSE:To eliminate the hard-to-see characters, etc., in a character in a character multiplex mode or a TV game mode. CONSTITUTION:A system control microcomputer 4 selects the video signal that should be inputted to an input signal switch circuit 6 in response to the mode set at an input setting part 2. When an on-air mode or a video mode is set, a velocity modulation circuit 10 is kept active. At the same time, the scanning velocity of an electronic beam is controlled in adverse proportion to a luminance level and then the contour is emphasized. When a character multiplex mode or a TV game mode is set, an operation stop signal SSTOP is sent to the circuit 10. Thus the operation of the circuit 10 is stopped so that the over-emphasis of contour and the compression done in the horizontal scanning direction can be evaded. Under such conditions, the easy-to-recognize characters, etc., are displayed on the screen of a CRT 12.

Abstract: PURPOSE:To prevent the peeling of a film in the peripheral part of the mask by forming a mask substrate to be coated with the film of a resist, etc., to a circular shape or a polygonal shape approximate to the circular shape and forming the substrate to a curved surface shape bulging the outer peripheral edge. CONSTITUTION:The mask substrate 3 to be coated with the film 2 of a resist, SOG(spin on glass), etc., on its surface is formed to the circular shape or the polygonal shape approximate to the circular shape and in addition, its outer peripheral edge is bulged to facilitate the trimming of the outer peripheral part of the mask. Since the mask substrate 3 has not projecting parts, the surface of the substrate 3 is uniformly coated with the coating film 2 of the resist, etc., up to the outer periphery even if this coating film is formed thereon. Further, the outer peripheral edge is bulged and, therefore, the trimming of the spin coating film 2 of the resist, etc., in the outer peripheral part of the mask is possible. Then, the film peeling in the peripheral part of the substrate 3 does not arise even if handling, etc., are executed. Since the adhesion of the peeled film as a dust source on the mask does not arise, the generation of a transfer defect at the time of processing is not executed.

Title: Manufacture of semiconductor device
Inventor: KOMINAMI MASANORI
IPC: H01L21/302
Filed: 1990-07-03
Abstract: PURPOSE:To enable a semiconductor device with less working failure ratio to be produced with a high yield by measuring luminous spectrum which is emitted when etching a nitride film for determining end point of etching. CONSTITUTION:End point of etching is determined by measuring luminous spectrum which is emitted when etching a nitride film. Namely, while a nitride film is being etched, a peak of three luminous spectra due to nitrogen is detected near 350nm. However, if etching advances exceeding the nitride film, the peak at 350nm cannot be observed any more. By utilizing this phenomenon, detection of etching end point can be performed highly accurately, thus enabling a semiconductor device (for example, FET) with less working failure rate can be produced with high yield and with a stable quality.

Title: Photographic printer and exposure method
Inventor: NARITA TOSHIHIKO
IPC: G03B27/46
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To improve the picture element density of a print by suppressing the rising of the cost as low as possible. SOLUTION: After a picture is displayed on a liquid crystal panel and a photographic printing paper 54 has a picture exposure, only the printing paper 54 is carried by a distance Y on the printing paper 54 corresponding to the picture element pitch of the liquid crystal panel, to execute the picture exposure again. Thus, the picture exposure is attained in regions 126 to 131 shifted from regions 120 to 125 exposed in the first time on the printing paper 54 by the distance Y respectively, to increase the density of the exposed part in the printing paper 54. Therefore, the picture element density of the print can be improved while the rising of the cost is minimized, without installing a piezoelectric element.

Title: Trimming camera
Inventor: KUDO YOSHINOBU
IPC: G03B27/34
Filed: 1989-07-10
Abstract: PURPOSE:To obtain suitable normal and pseudo telephotographic prints by varying the irradiation angle of a flashing means with a change in the pseudo focal length of a photographing lens. CONSTITUTION:When an electronic flash 3 is flashed to take a zoom picture through a photographing lens 1 under a mode (first mode) where the irradiation angle of the electronic flash 3 is automatically set, the irradiation angle of the electronic flash 3 is set according to the pseudo focal length set by an electronic zoom, and an object equivalent to the trimmed scope of a film is suitably irradiated with stroboscopic light. Under a mode (second mode) where the irradiation angle of the stroboscope 3 is manually set, a photographer can set the irradiation angle of the stroboscope 3 regardless of the pseudo focal length set by the electronic zoom, and can adjust electronic flash light so that the object equivalent to the untrimmed part of the film is suitably irradiated with electronic flash light. Consequently, a proper photographic print is obtained even if the film photographed by the electronic zoom is printed without being trimmed.

Title: Voice packet receiver
Inventor: ISHIZUKA TOSHIO
IPC: H04L12/00
Filed: 1993-07-19
Abstract: PURPOSE:To simplify the voice reproduction processing and to improve the processing capability by omitting the validity check of the sequence number of a received voice packet and the processing of holding a voice frame in the case of abnormality detection. CONSTITUTION:A voice signal composed to be a packet having a sequential number from a coded voice frame is received and a packet inverse conversion section 1 reproduces the voice frame. In this case, an arithmetic section 2 calculates a buffer number used to store a voice frame based on the sequence number of the voice packets and writes the result to a buffer memory 6 via a selection circuit 5. Then a read buffer number arithmetic section 7 gives a number counted by a signal from a timing generating section 9 to the buffer memory 6 to read the voice frame sequentially from the memory 6. Then a write means 8 writes and stores a compensation voice frame replacing a missing voice frame due to a missing packet to a location corresponding to the buffer memory 6. Thus, the voice processing is simplified and the processing capability is improved.
